What is the best sporting event in the world?

Ey guys of the world!!!!
It´s my first day here with you all. Yesterday, here in Spain, was played the most popular football (soccer) match in our country, FC Barcelona against R.Madrid, was played. It was viewed by more than 400 million people all over the world, even more than the worldwide known world famous superbowl of America.
I want you to tell me about, in your opinion, what is the most important sports event in the world and why?
As I said before it´s my first day here and I would like to meet people in order to improve my english. On the other hand I can do my best to help you with your spanish.
Have a nice day ¡¡¡, be happy ¡¡¡¡
